2ch amp and HT receiver connected to same speakers

I listen to 95% music and 5% home theater. My 2ch system is a BAT pre and a Bryston amp, and I have an Integra receiver for theater. My BAT has a HT pass-through function, so that I can run my LR speakers off my Bryston amp. This setup causes a ground loop, however, and I've given up trying to eliminate it. So I wonder if I can connect both my 2ch amp and the LR outputs of my receiver to my speakers. Would this harm my amp (especially the Bryston)? Would it hurt the sound quality of my music? Thanks for any comments.

If the co-ax is hooked up to anything that is hooked up to the speakers where you hear the hum, it could be the co-ax. Of course, it COULD also be a bad cable somewhere in the system as well.

Install banana plugs on your cables for a quick disconnect when you switch between systems. Never run with both connected at the same time.

Summitav, are you saying that the CATV coax would cause a hum even if it is not connected to my HT receiver?

Sometimes yes. Chances are it has a connection somehwere, if even to the same electircal wiring in your house.

It is simple enough to listen for the hum, and just unscrew the coax (AT THE WALL)

If the HUM stops, then you know the cause.

Then to find out what to do about it.
